m m v g M m 2% M i M m h r M. 0 fl Inhalers, of which the following is a specifi uuirn STAT Y E A NEW 103 i To all whom it may concern:

Be it known that I, WILLIAM HENRY SGHAEFER, a citizen ofthe United States, residing at New York, county of New "York, and State of New York, have invented certain new and useful Improvementsin cation. 7 1

The object of the present invention is'an improvement in inhalers of the type desired in my co-pending application, Serial No. 301,53 1 filed June. 3rd, 1919, of which this is a continuation in part.

It is the object of my invention to provide an 'inhaler'of a very simple and compact construction which can be readily carriedby the user on his person and which is constructed of a non-corrosive material so that it will not be injurious in any way to a patient. I

A further object of the invention isthe provision of an inhaler in which the material absorbing the medicament is contained in a perforated and split metal sleeve constituting means for conveniently holding the inhaler tube in its socket, thus making the provision of special fastening means unnecessary.

These and other objects will become apparent as the description of the inhaler proceeds reference being had to the accompanying drawing, in which Figure 1 is a side elevational view showing a modified form of construction, parts being broken away.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1.

Fig. 3 is a detail view of the sleeve holding the medicated material and its socket, the parts being assembled.

Fig. 4 is a similar view with the parts separated, and,

Fig. 5 is a rear view of the inhaler.

Fig. 6 is a plan view of the sleeve or tube.

Referring to the drawings in detail, the numeral 10 indicates a hollow cylindrical body preferably made of glass, having an open lower end, the upper end being contracted upon opposite sides and formed in tegrally with the contracted portion 11, are a pair of slightly conical tubes 12, separated by the space 13, and containing relatively small orifices 14, the tubes being so positioned as to readily enter the nostrils of an ordinary person.

Application-filed June 29,1920; Serial 110,392,762.

Integrally formed: with thecylindrical body 10- isa curved hollow arm or tube 25,

the element '25; extending upwardafrom sa-id body'and merging with the curve 27 into the mouth engaging portion 28,. terminating in. a substantially ball-shaped enlargement having a frontal opening29. The body ,10 preferably has an open lower end and at its upper end -is...formed into apa-irof slightly conical tubes l2 separated by the space} 13 and containing relatively small ori'ficesflt. The; tubes 12 being so. positioned as to readily enteri-the nostrils of an ordinary person. :Thelower end of the-inhaler isconstituted by a socket orv cap 80 having a flange 31 adapted to-be engaged by-the thumb and fingers of an-operator, and extending inwardly from the cap is an annular resilient sheet 32 vhavinga plurality of" perforations 33 The resilient sheet 32 'isslitted and rolled up into a tubehaving its 'slitted ends. 34 and 35ioverlappingflthe other ends, the ends 3 1 and 35. being sepa= rated by a horizontal slot 36 so that the ends are adapted to spring outwardly and engage with the interior wall of the cylindrical body 10, and of the cap 30 so as to be held firmly in engagement therewith.

The sheet or sleeve 32 is adapted to receive a cellular substance 87 as sponge or the like, previously impregnated with any desired medication whatever.

In operation, the nasal tubes 14: having been'placed in the nostrils, the device may be used as a simple inhaler by inspiration of the breath through the nostrils, in which case the air, laden with the medications will I pass through the passages of the nose or the same may be forced through, by blowing in the tube 25, creating sufficient pressure to It is to beunderstood that the inhaler body, while preferably made of glass, por

'force the medicated air through the passages celainor like material, may also be con-3 structed of metal of a non-corrodible nature, or plated so that the drugsormedieaments used have noeifect upon the same.

The disclosure is to be regarded as deb-v scriptive only and not as restrictive or limi"-f tative of the invention, of which obviously an embodimentmay be constructed includ ing many minor modifications without departing from the general scope herein indidated and hereinafter claimed.

I am aware that various devices for simi;

lar purposes have been the subject'of prior invention and can be found upon the market, and I do not desirethe resent invention to be confounded therewit but what I do claim as new and desire to secureby Letters Patent is-- a a i lkAn inhalerccomprising 'a cylindrical body, a pair of conical tubes formed intewith a medicament. a

2. An inhaler 11 comprising a cylindrical body, a pair of 1 nostril engaging tubes formed integrally therewith, a hollow mouth stem secured in a plane atright an- ,gles to said tube, a flanged cap adapted to receive the lower open end of said body, resilient means engaging with said cap wherebysaid cap is held in its body engaging position, constituting a perforate sp1it sheet rolled up into a tube with its slitted end overlapping the other end, the tube being carried by the cap and adapted to receivea; means removably engaged in said tube for holding medicaments.

3. An inhaler of the character described, comprising a v cylindrical body, a pair of nostril engaging tubes integrally formed With said body, a .hollow substantially S- shaped stem on sai'd body, a substantially ball-shaped mouth-piece at the upper end of said stem provided-with a round; opening at its frontal end part, a flanged cap adapted toengage the lower endof the said body, a perforated metal sheetrolled'up into atu be" with one end overlapping the other end, the tube being carried by the, capand adapted to receive the medicated material, said overlapping end-being divided by a v horizontal slot into two parts, the upper part to engage the inner wall of said body and the lower part to engage the inner wall of said cap for firmlyholding theparts together with frictional contac signature.
